HPI Savage 21 Front Coil Spring 1.6mm for 115mm Damper SAV13170/SP by GPM  [SAV13170/SP]

Front coil spring overview

This front coil spring is made for HPI Savage 21 setups and uses a 1.6mm wire diameter, sized to work with 115mm long dampers. The part is supplied as the listed item and is intended for shock replacement or a spring swap when tuning the front suspension on Savage 21 models.

Fitting follows common shock service practice: remove the shock from the chassis, take off the shock cap and shaft, withdraw the old spring, place the new coil spring onto the shock body or spring perch, then reassemble and check travel and preload. After installation adjust ride height and damping to dial in the handling you want.

From a tuning perspective, the 1.6mm wire and compatibility with 115mm long dampers give a predictable spring rate useful for adjusting front-end support and balance on HPI Savage 21 vehicles.
